Putting 0 in for x: 25 sin (pi/30)( 0 + 15) +35 = 25 sin (pi/30)(15) + 35= 25 sin15 pi/30 + 35= 25 sin pi/2 + 35= 25 (1) + 35 = 60

Yes, and this is the equation! You could write a cosine equation, and everything would be the same, except for the phase shift

You could write a version of this for degrees, instead of radians-- substitute 180 for pi and you'll have it!

I don't think the formula works, like for example when I plug in 0 into x it doesn't give me 6005/28/20
